Seven autochthonous cases of schistosomiasis mansoni are described in this paper. All of them refer to children, 3 to 13 years old, living in Planaltina, Federal District, Brazil. Five out of the seven cases belong to the same family living for 14 years in Planaltina. For the last 4 years this family has lived in a wooden hut 40 meters distant from a breeding place of B. glabrata. Of the 229 snails examined, two were naturallv infected with S. mansoni.
